DefaultEndpointRestrictions is only used in the module,
so this renames it to defaultEndpointRestrictions.

There's no need to explicitly add break after every case, as switch
statements will break automatically.

Prepare to support watch by cleaning up the conversion method and
splitting out each transition into a smaller method.
Kubernetes-commit: 63c49ba55a8da571522a9615dfa64471c5e9041e
Make setLink and setListLink the same, and make them happen in transformResponseObject.
Make those methods also responsible for ensuring an empty list. Then move outputMediaType
negotiation before all other calls in the specific methods, to ensure we fail fast.
Refactoring in preparation to support type conversion on watch.

- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

Kubernetes-commit: 954996e231074dc7429f7be1256a579bedd8344c
Added tracing for use cases where etcd is not the cause of long running
requests.
Fixed spelling.
Factored in Wojtek-t feedback.

Watch can return type "ERROR" and a metav1.Status object. We need to
handle that during wait, and make it easy to handle the status object.
Kubernetes-commit: 5a8afa073f6b8cbb8b09f997f6db747c39dffb6e
- Added metav1.Status() that enforces '406 Not Acceptable' response if
protobuf serialization is not fully supported for the API resource type.
- JSON and YAML serialization are supposed to be more completely baked
in, so serialization involving those, and general errors with seralizing
protobuf, will return '500 Internal Server Error'.
- If serialization failure occurs and original HTTP status code is
error, use the original status code, else use the serialization failure
status code.
- Write encoded API responses to intermediate buffer
- Use apimachinery/runtime::Encode() instead of
apimachinery/runtime/protocol::Encode() in
apiserver/endpoints/handlers/responsewriters/writers::SerializeObject()
- This allows for intended encoder error handling to fully work, facilitated by
apiserver/endpoints/handlers/responsewriters/status::ErrorToAPIResponse() before officially
writing to the http.ResponseWriter
- The specific part that wasn't working by ErrorToAPIResponse() was the
HTTP status code set. A direct call to
http.ResponseWriter::WriteHeader(statusCode) was made in
SerializeObject() with the original response status code, before
performing the encode. Once this
method is called, it can not again update the status code at a later
time, with say, an erro status code due to encode failure.
- Updated relevant apiserver unit test to reflect the new behavior
(TestWriteJSONDecodeError())
- Add build deps from make update for protobuf serializer
50342: Code review suggestion impl
- Ensure that http.ResponseWriter::Header().Set() is called before http.ResponseWriter::WriteHeader()
- This will avert a potential issue where changing the response media type to text/plain wouldn't work.
- We want to respond with plain text if serialization fails of the original response, and serialization also fails for the resultant error response.
50342: wrapper for http.ResponseWriter
- Prevent potential performance regression caused by modifying encode to use a buffer instead of streaming
- This is achieved by creating a wrapper type for http.ResponseWriter that will use WriteHeader(statusCode) on the first
call to Write(). Thus, on encode success, Write() will write the original statusCode. On encode failure, we pass control
onto responsewriters::errSerializationFatal(), which will process the error to obtain potentially a new status code, depending
on whether or not the original status code was itself an error.
50342: code review suggestions
- Remove historical note from unit test comment
- Don't export httpResponseWriterWithInit type (for now)
Kubernetes-commit: bcdf3bb64333ce12f15b1beebef48f554d69027f
This ensures that request cancellation will be propagated properly to
the client used to create the stream. Without this fix, the apiserver
and the kubelet may leak resources (e.g., goroutine, inotify watches).
One such example is that if user run `kubectl logs -f <container that
don't produce new logs)` and then enter ctrl-c, both kubelet and
apiserver will hold on to the connection and resources indefinitely.
Kubernetes-commit: 31d1607a514b62ef46452e402f5438d827314b98
Make apiserver pass connectRequest.Options directly to the admission layer. All
the information in rest.ConnectRequest is present in admission attributes.
Kubernetes-commit: 355691d310803ea3a0cd8ff284a39ead38857602
This makes the error consistent with the timeout filter and also helps
the user understand that they requested a specific timeout.

builds on #62868
1. When the incoming patch specified a resourceVersion that failed as a precondition,
the patch handler would retry uselessly 5 times. This PR collapses onto GuaranteedUpdate,
which immediately stops retrying in that case.
2. When the incoming patch did not specify a resourceVersion, and persisting to etcd
contended with other etcd updates, the retry would try to detect patch conflicts with
deltas from the first 'current object' retrieved from etcd and fail with a conflict error
in that case. Given that the user did not provide any information about the starting version
they expected their patch to apply to, this does not make sense, and results in arbitrary
conflict errors, depending on when the patch was submitted relative to other changes made
to the resource. This PR changes the patch application to be performed on the object retrieved
from etcd identically on every attempt.
fixes#58017
SMP is no longer computed for CRD objects
fixes#42644
No special state is retained on the first attempt, so the patch handler correctly handles
the cached storage optimistically trying with a cached object first
Kubernetes-commit: fbd6f3808480d27a83643e82a11c217601b76cbc
Removed automatic registration with `init` funciton and use `Register` function
to register metrics for etcd storage only when requested.
Kubernetes-commit: 40cf7880135b56e2d88a04d5fce08303b249eb34
This is the combination of a series of changes which individually don't
make any behavioral changes. The original commits are preserved in my
own fork in the refactor-patch-complete branch, as when squashed this is
impossible to review.
This turned a big function with lots of parameters and closures into an
object with multiple functions, fewer closures and more well documented
state transitions.
Kubernetes-commit: 349a99b80e7e6c0c92218c814ae0858fd71609fc
The registry abstraction is unnecessary and adds direct coupling to the
core types. By using a wrapper, we carry through the default
implementations of the non-mutating operations. The DeleteCollection
method is explicitly patched out since it cannot be correctly
implemented on the storage currently.
As a result, TableConvertor is now exposed.
A few other minor refactorings
* Corrected the case of some variables
* Used functions instead of methods for several helper methods
* Removed the legacy Deleter - service was the only remaining consumer
Kubernetes-commit: 110b064d630ca39220696225dd597e7d33b95f4f
Since we have a custom handler for apiextensions-apiserver,
we need to record the metrics here.
